使用 fancyvrb 和列表在 Verbatim 中执行 LaTeX 命令

Question

我正在尝试将诸如\textbf、、\textit之类的 LaTeX 命令\textcolor与fancyvrb结合使用listings。特别是我想同时对任何文本或整个 Java 代码块（不仅仅是关键字）进行加粗和着色。

所以我的\lstset选项没有设置 keywordstyle，这样我就可以对代码的任何部分进行加粗、着色。我有下面使用的示例 LaTeX 代码，但只有命令\textit有效。该\textbf命令不起作用。如果我尝试组合\textbf并\textcolor像

\textcolor!red|!\textbf!package com.test3;||

我遇到了一大堆错误。我在下面粘贴了我的示例代码...

\usetheme{bars}

\usepackage{xcolor}
\usepackage[T1]{fontenc}
\usepackage{hyperref}
\usepackage{listings}

\usepackage{mathtools}
\usepackage{fancyvrb}

为 Verbatim 环境定义一个可选参数：

\documentclass{beamer}
\usepackage[T1]{fontenc}
\usepackage[scaled=0.85]{beramono}%% monotype with bold variant  
\usetheme{bars}

\usepackage{xcolor}
\usepackage[T1]{fontenc}
\usepackage{hyperref}
\usepackage{listings}
\usepackage{setspace}
\usepackage{graphicx}
\usepackage{subfiles}
\usepackage{alltt}
\usepackage{mathtools}
\usepackage{fancyvrb}

\setcounter{tocdepth}{1}

\lstdefinestyle{JavaPlain}{ %
basicstyle=\scriptsize\ttfamily, % the size of the fonts 
numbers=left,                   % where to put the line-numbers
numberstyle=\tiny,      % the size of the fonts that are used for th
stepnumber=1,                   % the step between two line-numbers
numbersep=5pt,                  % how far the line-numbers are from the code
backgroundcolor=\color{white},  % choose the background color
showspaces=false,               % show spaces adding particular underscores
showstringspaces=false,         % underline spaces within strings
showtabs=false,                 % show tabs within strings adding 
frame=single,           % adds a frame around the code
tabsize=2,          % sets default tabsize to 2 spaces
captionpos=b,           % sets the caption-position to bottom
breaklines=true,        % sets automatic line breaking
breakatwhitespace=false,    % sets if automatic breaks should only happen
fancyvrb=true,
}

\newcommand\Red[1]{\textcolor{red}{#1}}
\newenvironment{JavaCodePlain}[1][]
  { \VerbatimEnvironment%
    \begin{Verbatim}[#1]}
  { \end{Verbatim}  } 

\begin{document}

\begin{frame}[fragile]
 \frametitle{Latex commands in Verbatim}
   \begin{JavaCodePlain}[commandchars=\\!|]
   \textbf!package com.test;|  // This does not become bold
   \textit!package com.test2;| //This is italicized
   \Red!\textbf!package com.test3;|| //Whole bunch of errors

    public class Employee {
      ...
    }
  \end{JavaCodePlain}
\end{frame}

\end{document}

但是，您应该使用具有粗体变体的 monotype 字体，例如beramono：
